Abstract

The invention relates to a device for regulating the energy supply for ignition in an internal combustion engine, comprising an ignition coil and a central control unit (16). Said ignition coil has a primary winding (4) and an ignition power module (13) which is connected to said primary winding (4). The central control unit (16) determines a time difference between the point at which current begins to flow through the primary winding (4) and the point at which the primary flow reaches a first threshold value and establishes the additional power loss of the ignition power module (13) caused by shorted coils in the primary winding (4), based on said time difference, and/or the reduction of active energy. When the additional power loss of the ignition power module (13) exceeds a power loss threshold, the ignition power module is deactivated. The active energy is regulated by a regulating unit (163) of the central control unit (16), preferably through the closing time, with the objective of minimising the reduction of active energy.
